Partner strimmer will not start?

Hi Can anyone help please.
I have a Partner Calibri strimmer (trimmer) that refuses to start.
I have fuel getting through and a lovely spark and occasionally it will fire for a brief second but will not start.
I have cleaned the carberettor and plug etc.
Any advice would be great.

Turn down your high and low screws on the carb then turn them out 1 and 1/2 turns. That should allow it to start, but it will probably run rough. Once it is running you can adjust your screws to get it running right. First try blowing air in the air filter hole while starting; an old trick that just might work for you.
